Facts: What do we know about the school shooting?

Connecticut State Police responded to reports of a shooting at a Newtown elementary school Friday, Dec. 14, 2012, in southwestern Connecticut, according to police spokesman.

Key facts from the scene of the Connecticut elementary school shooting:

THE TOLL: 28 dead, including the gunman, Adam Lanza; his mother, Nancy Lanza; the elementary school’s principal, Dawn Hochsprung; and 20 schoolchildren. A woman who works at the school was wounded.

THE SUSPECT: 20-year-old Adam Lanza wore a pocket protector when he was in high school and was an honor student, and was called “remote” and “one of the goths” by classmates. A law enforcement official said he may have had a personality disorder. He grew up in an affluent neighborhood of well-tended homes with neighbors who worked as executives at companies like IBM. Police shed no light on his motive.

THE SCENE: Police told children to close their eyes as they led them past the carnage from their classrooms. The intercom broadcast screams throughout the school; others heard popping sounds, or, as a boy said, something that sounded like “cans falling.” Crying children were escorted through the school’s parking lot in line, hands on one another’s shoulders, as panicked parents raced to the school to find their children. Witnesses said the shooter said nothing.

WHERE THEY DIED: Most of the dead were found in two classrooms; Lanza’s mother, Nancy, was found dead at her home. The children killed were between ages 5 and 10.

GUNS: Two pistols, a Glock and a Sig Sauer, were found inside the school. A .223-caliber rifle was found in the back of the car that Lanza drove to school. Lanza’s mother had four weapons legally registered, and his father had two. A Henry repeating rifle, an Enfield rifle and a shotgun were also recovered by police; it was not clear where they were found.

THE FAMILY: Lanza’s mother, Nancy, was well-liked and was called a nurturing parent who enjoyed hosting dice games and preparing for the holidays. She divorced Peter Lanza, a tax director who lives in Stamford, Conn., four years ago. Lanza’s 24-year-old brother, Ryan, works in Manhattan and was questioned by police near his New Jersey home but is not a suspect. Law enforcement officials initially identified him as the suspect.

THE TOWN: Idyllic, 300-year-old Newtown is a postcard New England town that takes pride in a Lions Club river race that sells yellow rubber ducks for charity, features Halloween displays on Main Street houses, and is home to garden clubs and Christmas tree lightings. The Spencer Tracy-Katharine Hepburn comedy “Adam’s Rib” was filmed decades ago on a lake in the town, now a bedroom community of 27,000 where executives commute to Manhattan.

HISTORY: The shooting is the second-deadliest in U.S. history and one of the deadliest mass shootings around the world. A gunman at Virginia Tech University killed 33, including himself, in 2007. Only Virginia Tech and the mass killings of 77 in Norway in 2011 had greater death tolls across the world over the past 20 years.
